    17. Case of the Month Adjacent Implants Replacing Maxillary Central Incisors: The Keys for Success

    Background: One of the most challenging scenarios in dental implantology is the restoration of two adjacent central maxillary incisors. In such cases, a meticulous diagnosis, evaluation, and preoperative planning are necessary to achieve an esthetic outcome.

    29. The Dynamic Positive Pressure Sinus Augmentation Technique: A Description of the Technique

    The sinus floor elevation, or sinus lift procedure, is an internal augmentation of the maxillary sinus, which is intended to increase the vertical bony dimension in the lateral maxilla in order to make the placement of dental implants in posterior maxilla possible. The operation was conceived and introduced by Tatum at the Birmingham Alabama Implant Meeting of 1976. This technique has been modified through the years. The classic sinus lift operation consists of the preparation of a top hinge door (win- dow) in the lateral maxillary sinus wall. This door is luxated inward and upward together with the Schneiderian membrane to a horizontal position forming the new sinus bottom. The space underneath this lifted window and sinus mucosa is filled with graft material. The aim of this article is to describe a newly developed technique for sinus floor augmentation – the Dynamic Positive Pressure technique – aiming minimal invasive and atraumatic procedure and less surgical time. With this modified sinus augmentation technique, the risk for sinus membrane perforation and time consumption is decreased and there is reduced trauma to the patient reducing the inflammatory reaction and post-operative discomfort.

    37. Analyses of Heating Induced by Piezoultrasonic Devices During Bone Surgery

    Managing the periodontal bone environment is a continuous challenge for the periodontist. The health, esthetic and function of the periodontal tissues depend on the integrity of the alveolar bone. Various surgical techniques and protocols requiring bone surgery are available to treat bone loss caused by periodontal disease, extractions, infections or accidents. Most of these techniques are within the context of achieving osteointegrated endoosseous implants. With the recent developments in ultrasonic-assisted osteotomes, new surgical protocols are proposed. This paper presents a pilot research on the heating induced by this technique during the in vitro sectioning of animal cortical bone. The incisions were done using two powerful piezoultrasonic devices: the PiezosurgeryTM (Mectron®, Italy), the Piezo®tomeTM (Satelec , France) and a conventional drill. These were then compared and assessed by infrared thermography in order to determine the heating of bone produced during sectioning.
